Title: Video display systems
IPC: G09G5/22
Filed: 1970-10-23
Abstract: 1336597 Cathode-ray tube display FUJITSU Ltd 23 Oct 1970 [25 Oct 1969] 50571/70 Heading H4T An arrangement for displaying characters and also vertical bar graphs on a cathode-ray tube by selective bright-up during a raster-type scan comprises, in addition to a memory store for the incoming character codes and a character generator converting these codes into video bright-up signals, an arrangement for comparing codes representing the tops of bar graphs with the contents of a counter holding the current scan-line number and ordering bright-up signals when the scan-line number is greater. The data for display is received as a sequence of 7-bit groups in series-parallel mode, each group representing either (a) an alphanumeric character for display (top and bottom rows and lefthand column, Fig. 2) or (b) an indication that bar-graph data is to start or has ended (columns 2 and 8 of rows 2-5, Fig. 2), or (c) a bar graph height (columns 2-7 of rows 2-5). These 7-bit groups are held in circulating stores and transferred, a row at a time, to further circulating stores (buffers) where they are read out at 10 consecutive scan line times to control the display; this read-out is in parallel on lines T1- T7 (Fig. 4). A counter Reg 2 receiving scan-line signals ST counts up to ten (seven display lines and three inter-row lines) and provides on S1-S3 a binary-coded output of the scan-line numbers 1-7 which in conjunction with the character decoder D1 (recognizing characters for display) controls the generation from a magnetic core matrix read-only store PM of the bright-up signals for the seven successive scan lines (e.g. lines 11-18, Fig. 2). These signals; five bits for each character, are transferred in parallel to dynamicizer Reg 3 where they are read out by clock pulses CCT and passed (assuming #K=1) via AND gate A43 to the video amplifier VAMP. When a start-of-bargraph code is identified (e.g. row 2, column 2, in Fig. 2) in code detector DET, output K is switched to 1 to open A41 and close A43, and subsequent 7-bit codes representing the levels of the tops of the bar graphs in columns 3-7, Fig. 2, are compared in Reg 1 with the scan-line count and if the latter is equal or greater a signal of duration equal to five clock pulses is passed to A41 to generate five bright-up pulses for that column. At the same time the codes held in the buffers are caused to recirculate therein not only for the ten scan-line periods representing a character row but also for subsequent character rows while K is set. On receipt of an end-of-bar-graph signal (e.g. in column 8, Fig. 2) K, K return to 0, 1 for character display.

IPC: C10G67/06
Filed: 1963-12-23
Abstract: A process for the purification of a hydrocarbon distillate oil, in particular light distillate and kerosine, which contains sulphur, by the removal of sulphur therefrom, comprises a conversion stage in which the distillate vapours mixed with a hydrogenating gas containing oxides of carbon, are reacted in the presence of a hydrodesulphurization catalyst to convert the sulphur present in the distillate to hydrogen sulphide, and at least two separated absorption stages in each of which the mixture of gases and vapours resulting from the conversion stage is passed over a mass of material for absorbing hydrogen sulphide, whereby the sulphur content of the mixture is reduced to the desired degree.  There may be a further conversion stage between the absorption stages, and still further conversion and absorption stages following the second absorption stage.  The process may be carried out at 250-450 DEG  C. and up to 50 atmospheres.  The catalyst may be molybdenum on alumina, activated with nickel. The absorbent may be iron oxide.  The process is applicable to straight-run naphthas and kerosine.

Title: Process for continuous biaxial stretching of plastic film webs
IPC: B29C55/14
Filed: 1963-12-27
Abstract: 1,058,090. Films. KALLE A.G. Dec. 27, 1963 [Dec. 29, 1962], No. 51034/63. Heading B5B. In the continuous biaxial stretching of a synthetic plastic film, the film is first stretched transversely and then longitudinally between feed and draw roller systems with limitation of the resulting transverse shrinkage, the transversely stretched film being caused to pass through the feed system at a temperature at least 10‹ C. and preferably at least 30‹ C. below the longitudinal stretching temperature after which it is brought to the said temperature. After the longitudinal stretching, while maintaining the effect of means for limitation of transverse shrinkage but without further longitudinal stretching, the film may be heated to a temperature above the stretching temperature but below the melting point of the film, cooled, and the said limitation effect discontinued. The film may be heated above ambient temperature prior to passing through the feed roller system, and heating and/or cooling of the film before and after stretching respectively may be effected by air blasts at suitable temperatures, such heating being with or without additional radiant heating. Desirably, limitation of transverse shrinkage resulting from longitudinal stretching is effected by maintaining the film under transverse tension without essentially influencing any stage of the longitudinal stretching resulting from the co-action of the feed and draw-off systems and the heating of the film. If desired, however, the speed of forward movement of the clips, e.g. within the stretching zone, may be increased by externally acting advancing means which transmit only so much frictional force that the clips do not overrun the film. Stretching of polyethylene terephthalate films is described. Apparatus as shown comprises spaced feed and draw roller systems Z 1  and Z 2 , two series of non-interconnected clips (not shown), adapted to grip the margins of the film and carried in guide rails R 1  and R 2 , and return guide rails R 3 , R 4 , heating means for the film issuing from the feed roller system, cooling means for the film before entering the draw roller system, and heating means (pre-heating rollers W 1 , W 2 , W 3  and W 4 ) located in front of the entry to the feed roller system. Said heating and cooling means may include means for delivering air blasts. The guide rails are advantageously arranged so that they converge slightly from the beginning to the end of the longitudinal stretching zone, the angle of convergence being only a few degrees. The apparatus may be modified to permit subsequent heat-setting of the film by replacing the draw roller system Z 2  with one or two pairs of rollers so shaped that they engage only that part of the film surface not gripped by the clips, and also extending the clip guide rails, the clips being opened only after completion of the heatsetting step. In this case each pair of rollers consists advantageously of a rubber-sleeved roller and a steel roller.
